Clamp for pipes



CLAMP FOR PIPES Filed arch 12,

Patented Jan. 6, 1931 UNlTEDe-STATES PATENT OFFICE VICTOR I-I. HARBERLOF CHICAGO, ILLINOIS, ASSIGNOR TO ILLINOIS RAILWAY EQUIP- MENT ooMrANY, A CORPORATION or ILLINOIS t CLAMP ron rIPEs My invention relates to means more especially intended for clamping and irmly holdingthe air pipes of air lbrake systems in place and especially means for properly securing theairy pipes disposed longitudinally through which the air pipes areusually disposed. u

The .construction and its application will be readily comprehended from the detailed description ofthe accompanying drawing,

whereint v Figure 1 is a plan view of my improved means applied to a portion of pipe and an element Yor cross member of the car underframe which is shownin section.

Figure?, is a perspective view of one oi' the complementary members of the clamp.v

Figure 3 is a perspective view of the other complementary member of the clamp.

vFigure 4 is a side elevation illustrating a modified vform of my improvedclamp'in its application to the car underframe, a portion whereofl is shown in section, together with a portion of the pipe.

In the particular exemplii'cation of the invention as disclosed in Figure 1, 10 illustrates a portion of the air pipe or line which constitutes a part of the' air brake system of a railroad car. The invention is shown in its especial adaptation to the pipe which is disposed longitudinally beneath the car. In present railroad practice, these air Ypipes 'in most instances are made topass through suitable apertures or openings in the'diaphragmsY of the transversely disposed members of the car underframe; a portion ofsuch transverse'pon.

tion ofthecar underframebeing indicated at `-12 through which the 11 provided with an opening therethrough at air pipe 10 passes.

In order to prevent improper movement of the airline or pipe, which would result from the severe shocks or jars encountered by railroadl cars in operation and to prevent improper chatter and vibration, I have provided clamping means comprising the substantially semi-cylindrical lower member 13 shown in Figure 2 formed to provide a suitable seat for the air pipe or line; with the lower outer surface of the member'13 provided with a pair of spaced and transversely disposed arcuate ribs 14. As the member 13 is intended to be disposed through thev aperture 12 in the car underframe element 11, the ribs 14 are spaced apart a distance sulcient toireceive the diaphragm or web portion 11 of the car underirame therebetween, with the result that when all of the elements have been properly assembled, longitudinal movement of member 13 will be impossible because of the straddling yrelation between the ribs 14 and the diaphragm or web portion 11 of the car underframe.

One ,end of member 13 is provided with a laterally disposed lug or arm 15 which is preferably slotted as at 16 for the purpose or" receiving' a suitable bolt 17. One side of the lug orarm 15 is shown provided with shoulders or lugs 18, 18 adapted to provide abutment for vthe head 19 of the bolt and thereby prevent its rotation; the shoulders 18 beingadapted to engage one of the flat faces or sides of the bolt as shown in Figure 1.v4 v

` After member 13 has been inserted through the, aperture 12 in the car underframe element `llin the manner described-and the pipe 10 has been seated therein, the clamp member shown in Figure 3 is then put into place longitudinally of. the side of the pipe opposite to that on-which member 13 is located. Member 2O consists of a substantially semi-cylindrical element, preferably of length somewhat greater than element 13 and adapted to partially encircle the pipe without, how ever, having its longitudinal edgescontact with the longitudinal edges of member 13.

v., The member 20 is preferably made of increasing thickness toward one end; that is to say like member 13 and is intended toepasse through the opening 12 inthe car yunder-V 1 frame member 11. i

WV ith member 20.made somewhat longer than memberrl", itis apparent that'the endfv having arm 21 will be disposedfsomewhat beyondftheendooffmember lhaving arm 1.5, Y

andthereforey will be disposed, a distance fartherl removed from the car underframe `member 11. s member 1,3( will be, held against longitudinal'movement by the spaced lips 14, 14 which interlock with` the car underframe member 11, itis evident when bolt `17 haslbeen, disposed through'theiapertures arms and21, respectively, that screwingf up of thenut 28 will' cause, member 20tto be drawn toward thecar underframemember 11'.V

With vthe member 2Ov provided with` ata: i

peredV surface, namely with a surface increasing-vin thicknesstoward the end having arm4 21, itlis apparent that. a rm wedging rela,- tion with the :car underframe member. 1 1will` be provided, and as. aresnlt the'variousoele ments' of the clamp andthe airpipe or line will be firmly wedged inplace inthe aperture in the car underframe and. movement or vi.- bration of the pipe ,or line made impossible.y

ln Figure 4 I illustrate a modification; of the invention, k in-thatthe one or bottom mem-v ber 241 is substantially similar tomember 13 except thatfitis not p rovdedfwith..the.later-y ally disposedflug or arm` 15:; member 24, Ihowever, having v the spaced, circumferentially.

It is obvious from the construction shown in Figure 4 that when bolt29 has been inserted through the diaphragm 11 of the car underframe member and the arm 27 and nut 81 is screwed up tightly'ion the bolt,rmemberu 26 will be forced lengthwise of the pipe `10, namely in a direction moving the arm 27of thel member vtoward the car underframe element 11, thus firmly wedging the various ele-A mentsingpljace by reasonof the tapered sur face on member 26,7causing the pipe10 to berigidly'clamped between the members 24- and-Zalldvmembel 24: natu-r11flrm1yiheld in" place,. with theresult that improper ,or longitudinal movement of the air pipe will be impossible.
